Bob Lutz, former Vice Chairman of General Motors, has claimed that Tesla would be going out of business soon and urges those who want a Model S to buy as soon as possible.

According to an article by the Los Angeles Times, Lutz said in front of an audience full of vintage-car collectors in Scottsdale, Arizona: purchase a Model S “while they’re still available.”

For those who are wondering, Lutz is said to be a huge fan of the Model S but believes that the Tesla’s CEO “hasn’t figured out the revenues have to be greater than costs… when you are perennially running out of cash you are just not running a good automobile company.”

The electric vehicle company was reported last year to be going through nearly S$626k every hour which might be a tad high for a relatively new company.
